AI Technical Summary
Traditional metal connectors are heavy and prone to corrosion, while flat, needle-punched plastic parts cannot provide good adhesion and fixation.
The disc body is made of corrosion-resistant and lightweight material, and features deformable needles with spiral marks, including a pointed head and a needle shaft. The interior is equipped with elastic pads and pre-cracks. The spiral marks increase friction and the needle deformation generates continuous extrusion pressure to improve adhesion and stability.
It achieves efficient, lightweight, and corrosion-resistant connection, and improves the adhesion and stability between the connecting disc and the connected object.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, specifically to a connecting plate. Background Technology
[0002] In many industries (such as construction, grinding disc connection of floor grinding machines, grinding tool connection of glass products grinding, horticulture and plant protection, etc.), metal connectors are often used to connect components or structures in the corresponding industries. However, metal connectors are heavy and easily corroded. There is a need for a more efficient, lightweight, corrosion-resistant and easy-to-install connector to connect various components or structures.
[0003] Traditional metal connectors are heavy and prone to corrosion, while plain, needle-punched plastic parts may not provide good adhesion and fixation. Therefore, designing a connector with high adhesion and stability can better meet the requirements. Summary of the Invention
[0004] To address the problems of the prior art, this utility model provides a connecting disc, comprising: a disc body, wherein a plurality of needles are provided on one end face of the disc body, and the disc body is made of a corrosion-resistant and lightweight material;
[0005] The surface of the needle is provided with spiral marks;
[0006] The needle is a deformable structure.
[0007] Furthermore, the needle includes: a pointed head and a needle shaft;
[0008] The pointed head has a conical structure, the pointed head is a deformable structure, and the surface of the pointed head is provided with spiral marks;
[0009] One end of the needle bar is connected to one end face of the disc body, and the other end of the needle bar is connected to the large-sized end of the pointed head;
[0010] The needle bar has multiple layers arranged circumferentially on the disc body.
[0011] Furthermore, the pointed head has a hollow structure, and an elastic pad is provided inside the pointed head. The surface of the pointed head is provided with pre-cracks that communicate with the interior.
[0012] Furthermore, the elastic pad has a cylindrical structure, and the pre-crack extends vertically downward along the top of the pointed head.
[0013] Furthermore, the needle length is 2-10 mm, and the tip diameter is less than 3 mm.
[0014] Furthermore, the disc body is a disc-shaped structure formed by mixing nylon and glass fiber.
[0015] Furthermore, the side of the disc body is provided with annular threads.
[0016] The beneficial effects of this utility model are:
[0017] This application increases the friction between the connecting disc and the connected object by setting spiral marks on the surface of the needle, thereby improving the adhesion. The needle is a deformable structure. When the needle is inserted into the hole, it deforms under force, thereby generating a continuous compressive force between the needle and the hole wall, which increases the interaction force between the hole wall and the needle, and thus improves the stability of the connecting disc.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Please see Figure 1-2 This utility model provides a connecting disc, including: a disc body 1, wherein a plurality of needles 2 are provided on one end face of the disc body 1, and the disc body is made of a corrosion-resistant and lightweight material;
[0024] The disc body 1 is a disc-shaped structure formed by mixing nylon (such as PA6 or PA66) or high-strength plastic and glass fiber, and the side of the disc body 1 is provided with annular threads;
[0025] The surface of the needle 2 is provided with spiral marks 6, which can significantly improve the fixing effect of the connecting plate;
[0026] The needle 2 is a deformable structure;
[0027] The needle 2 includes: a pointed head 3 and a needle shaft 4;
[0028] The pointed head 3 has a conical structure and is a deformable structure. The surface of the pointed head 3 is provided with spiral marks 6.
[0029] One end of the needle bar 4 is connected to one end face of the disc body 1, and the other end of the needle bar 4 is connected to the large-sized end of the pointed head 3;
[0030] The needle bar portion 4 has multiple layers arranged in a circumferential direction on the disc body.
[0031] The pointed head 3 has a hollow structure, and an elastic pad is provided inside the pointed head 3. The surface of the pointed head 3 is provided with pre-cracks 5 that communicate with the interior. The elastic pad is a cylindrical structure, and the pre-cracks 5 extend vertically downward along the top of the pointed head 3.
[0032] The needle 2 has a length of 2-10 mm and a tip diameter of less than 3 mm.
[0033] This application utilizes a lighter nylon to make the connecting disc, and the spiral marks on the surface of the needle increase the friction between the connecting disc and the connected object, thereby improving adhesion. The needle is hollow inside and has pre-cracks on its surface. After the needle is inserted into the hole on the connected object, the gap between the pre-cracks becomes smaller, and the elastomer pad deforms, thereby generating a continuous compressive force between the needle and the hole wall, which increases the interaction force between the hole wall and the needle, and thus improves the stability of the connecting disc.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
